Passthrough
Using this option, it is possible to connect an arbitrary device
to the serial port and access it (assuming it provides terminal
support) via telnet. Select the appropriate options for the serial
port and use the Telnet Console (see Section
5.3.6
on page
31
)
or a standard telnet client to connect to LARA. For more infor-
mation about the telnet interface have a look at Section
5.7

.

device you have to enter an username and a password which must exist on the SPC and have the
privileges to switch power for each port.

Modem Settings
LARA offers remote access using a telephone line in addition to the standard access over the built-in
Ethernet adapter. The modem needs to be connected to LARA’s serial interface (refer to Figure
3.3
on page
10
).
Logically, connecting to LARA using a telephone line means nothing else than building up a ded-
icated point to point connection from your console computer to the LARA. With other words,
LARA acts as an Internet Service Provider (ISP) to which you can dial in. The connection is
established using the Point-to-Point Protocol (PPP). Before you connect to LARA, make sure to
configure your console computer accordingly. For instance on Windows based operating systems
you can configure a dial-up network connection, which defaults to the right settings like PPP.
The modem settings are part of serial settings panel (Figure
5.25
on the preceding page).
Table 5.13.: Description of all modem settings
